Multi-Lingual Bots

Consumers are more likely to engage with your bot if it can communicate in their preferred language. Kore.ai Bots Platform supports enabling multiple languages for a bot without having to rebuild the bot definitions.

You can build the bot in your preferred language and then enable one or more supported languages. As part of enabling the language, the platform automatically translates all Standard Responses and you can then translate various other bot elements in the new language.

Supported Languages

Bots Platform currently supports the following languages:

Default Language

You can choose a default language for the bot while creating it (see image below). Bot communicates with the user in the default language until the user’s language is identified. If the bot supports the user’s language, it switches to that language for the current or all of the following user sessions, depending on Bot’s Language settings.

Enabling Languages

Enabling a supported language to a bot involves the following steps:

Step 1: Enable a new language

Follow these steps to enable a new language for the bot:

1. Open the bot for which you want to enable other languages.
2. Hover over the side navigation panel select Settings > Config Settings and click Language Management.
3. From the list of Supported Languages, next to the language you want to enable, click Enable.
   
4. Clicking Enable opens the Enable Language – <Language Name> dialog where you have two options to enable the selected language for the bot – duplicate an existing language pack or creating a new language pack, as explained in Step 2 below.

Step 2: Create a language-specific version of the bot

You can enable a new language for the bot in the following two ways:

Option 1: Duplicate the default language

If you want to enable the new language for the bot quickly and translate the bot elements incrementally, you can begin by copying the configuration of the default language for the new language. It replicates the bot definition for the enabled language but continues to have all the bot elements in the default language, which you can translate from the application UI.

Follow these steps to create a new bot version by copying over the default language configurations:

1. On the Enable Language – <Language name> window, select Copy default language.
2. On the top-right corner of the window, click Enable. After a successful import, a prompt appears notifying that the new language bot is enabled.
   
3. After completing the previous steps, the bot definition gets created for the newly enabled language but the bot elements remain in the default language. You need to translate the bot elements from the UI.
4. Refer to the Translatable Bot Components section to view the complete list of bot elements for which you can add translations.

Option 2: Create a new language pack

You can create a translated version of the bot elements directly, perhaps with help from a language expert, by creating a JSON language pack for the enabled language.

You can download a JSON language pack of any of the already-enabled languages from the bot and then add translations in the JSON file.

Follow these steps to create a JSON language pack for the new enabled language:

1. On the Enable Language – <Language name> window, select Use <language-name> language configuration file option
2. From the Base Language Pack drop-down, select a language to download its language pack.
3. Click Download JSON.
   
4. The downloaded JSON file consists of various bot elements for which you should provide the translations. Refer to the Translatable Bot Components section to learn more about these bot elements.
5. To enter a translation for a bot element in the JSON file, replace the corresponding text with the translated text.
6. After customizing the downloaded JSON file for the new language, in the Enabling language pack field, click Choose File and upload the new language pack.
   
7. On the top-right corner of the window, click Enable. Upon successful import, the Import Successful window appears with the import results.
8. Click OK. Success prompt appears on the top-right corner of your screen.

• After you enable a new language, the status of all the published tasks that are modified to Configured. To make the new language work in the bot, you must re-publish the bot. Until then, the bot continues to function with the previously published languages.
• Support for Synonyms is restricted to English, French, Spanish and German languages. The respective sections in Natural Language and Entity Node will be in a disabled state for other languages.

Step 3: Add or edit translations

After enabling a new language for the bot, you might need to add or edit translations on an ongoing basis. You can make these edits from the application UI, which is particularly helpful if you have created the bot version by copying over the default bot configurations. Editing from the UI also helps when you want to make minor edits.
Note: If you need to make significant changes to the language pack, we recommend you to make the changes in the offline copy of the language pack and then upload it to the bot. Refer to Editing and Re-uploading a language pack to learn how to do it.

To add or edit translations to a bot element from the UI, follow these steps:

1. On the top right corner of the bot window, click the current bot language.
2. From the drop-down list, select the bot language in which you want to make the changes.
   
3. Enter the language-specific text for the selected bot elements, just as you did for the default language.
   For example, if you want to add a bot synonym in the new language, follow these steps:
   1. Hover over the bot’s side-navigation panel and click Natural Language > Synonyms.
   2. From the list of keywords and synonyms, click the keyword for which you want to add the synonym.
   3. In the synonyms box, type the synonym (in the enabled language) and press enter.

Editing and Re-uploading a language pack

If you need to make major changes to the language pack, the recommended practice is to make the changes in the offline copy of the language pack and re-upload it to the bot.

To re-upload a language pack to a bot, follow these steps:

1. On the top right corner of the bot window, click the current bot language.
2. From the drop-down list, select the bot language in which you want to make the changes.
3. Hover over the side navigation panel and click Settings > Config Settings -> Language Management. The Language Management window opens displaying a Manage button next to the enabled languages.
4. Click Manage and in the Manage Language window click Choose File and upload the updated language pack.

Language Detection and Selection

Multilingual bots auto-detect and switch language based on user’s utterance.

Language Detection

There are three ways a bot can detect the language based upon the user utterance:

• By Default: Kore.ai Bots platform uses its own language detection algorithm to detect language from the user utterance. This is the default setting and the end user’s language will be detected by the platform.
• For on-prem installation, you can go with the above-mentioned default setting of Kore.ai’s in-house language detection algorithm or use Google APIs for language detections. You can set it in the Kore Config file.
• If you are using BotKit SDK, you may also send the following cheat command from your BotKit to the platform:

  cheat language <language name or code>

Depending on the language selection configuration (see below), the bot continues to communicate with the user in the same language just for that single session or all the following sessions. In any case, if the user switches to another enabled language anytime later, the bot changes to the new language automatically.

If the bot fails to detect a user’s language with high confidence, it requests the user to select a preferred language from the list of enabled options.

Configuring the Language Selection Logic for Bot Users

1. On the Bot menu, click Settings > Config Settings -> Language Management.
   • Lifetime: The auto-detected language will be set as the user’s preferred language and used for all subsequent communications until the user interacts in another enabled language anytime later. If the user starts to talk in another enabled language, the bot changes to that language.
   • Per Session: Detects the user’s language at the beginning of every session and responds accordingly. Under Language Selection Logic (scroll down for the option), for language selection time frame, set to one of the following:
2. For testing and debugging purposes, you can override the language selection settings by using the cheat command during a chat session:
   Replace the language name or code with one of these values:
   • English: English or EN
   • German: German or DE
   • French: French or FR
   • Spanish: Spanish or ES
